Paolo's patch doesn't work for me. I run "crash" with the patch
applied,
crash crashed. Here is the debug output.

Paolo's patch doesn't work for me. I run "crash" with the patch
applied,
crash crashed. Here is the debug output.
Ok, at least the loading worked though. I'll take a look.

According to coredump, seems crash crashed at get_idt_base().
device_find_instance() fails to find "cpu" instance.

I think Dave already has a patch for this.
Paolo
The patch for get_idt_base() was put in crash version 5.0.4.
Looking back at the mail archives, though, I don't see what
version Gui is/was using?

Dave
Now I see with the crash debug output that Gui is using version
5.0.3. Can you please retry Paolo's patch on top of version
5.0.4?

Hi Dave,
I did apply Paolo's patch on top of version 5.0.4, the bug is still there.
I checked the 5.0.4 changelog and didn't see the fix for this.
Thanks
Gui
